Rinse the rice in a colander to remove naturally occurring toxins like arsenic.
Use a large or wide saucepan so the rice will have plenty of room to cook more evenly. If you have one, choose a heavy saucepan. Add water and salt, and bring to a full (rolling) boil. Add the rice and stir.
Allow the water to boil again, then turn to low. Cover and simmer for 40 minutes. (Set the timer and don’t look. Turn down if it starts to boil over.)
Remove from heat, keep covered and let stand 10 minutes, until water is all absorbed.
